MUSIC-SHEET TURNER.

Specification of Letters Patent.

Patented Sept. 1'7, 1912.

Application filed March 26, 1912. Serial No. 686,237.

To all YCZLOWL it may concern Be it known that 1, MICHAEL J. RYAN, a citizen of the United States, and residing at- Perth Amboy, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Music-Sheet Turners, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to devices or apparatus for turning sheet music, and the object thereof is to provide an improved device of this class which involves, in its constructlon, a suitable frame adapted to be mounted on or connected with a support of any kind or class, and which may also be mounted upon or in connection with a piano, organ, or other musical instrument, and by means of which sheets of music may be easily, quickly and conveniently turned both forward and backward; and with this and other objects in view the invention consists in a device or apparatus of the class specified constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification of which the accompanying drawing forms a part, in which the separate parts of my invention are designated vby suitable reference characters in each of the views, and in which Figure 1 is a front view of my improved music sheet turner with part of the construction broken away and part shown in section, and also showing sheets of music mounted thereon and. the central port-ions of which are broken away;-Fig. 2 a horizontal section on the line 22 of Fig. 1, and ;Fig. 3 a diagrammatic sectional plan view on the line 3-3 of Fig. 52.

My improved music sheet turner involves, in its construction, and in the form shown in the drawing, an oblong rectangular frame a comprising a horizontal upright base board a upright end members a and a horizontal top part or member a. The base board a is provided at the bottom thereof.

, with a flange a by which the frame may be thereof is mounted a vertical main tubular shaft 0 throughwhich is passed a supplemental shaft d, and the base board a of the frame is cut out centrally to form a space 6 to receive the lower ends of said shafts and said shafts extend downwardly through the ledge a, and secured to the front of the base board a? is a semicircular casing e which incloses or covers the lower ends of said shafts, and mounted on the lower end of the shaft 0 is a gear 0 and on the lower end of the shaft cl and below the gear 0 is a gear (1 The upper ends of the shafts 0 and d project above the top frame member a and said end of the shaft 0 is provided with an arm 0 and the corresponding end of the shaft d with an arm (i which is above the arm 0 and said arms are respectively provided at their outer ends with downwardly directed clips 0 and (l which are adapted to engage, or be connected with, the upper outer corners of the sheets of music supported on the frame a, and shown in Fig. 1 at f and f and said sheets f and f are provided, in the construction shown, with a back sheet f on the inner side of which the music is or may be printed, as well as on the sheets f and f Secured to the front of the base board a and at the right of the casing 6 is an oblong casing g, and the chamber 9 formed by this casing is in communication with the chamber 23 formed by the casing 72 at the back of the base board a.

Mounted in the casing Z) are two pairs of electromagnets lz,h and z'i and in the operation of the device the pair of magnets 71 h operate to give the shaft 0 a half revolution from rignt to left and back again from left .to right, while the pair of magnets ii operate to rotate the shaft (Z through a half revolution from right to left and back again from left to right, as will be hereinafter described. The pair of magnets h and b operate in connection with block armatures 11, and h carried on the opposite ends of a reciprocating bar h which is mounted in suitable bearings j, and said bar is provided centrally of its length with a transverse slot h adapted to receive a pin k carried on a swinging arm' b which is provided with a segmental gear It designed to mesh with, and partially rotate the gear 0' The pair of magnets i and 2' operate in connection with block armatures i and 2' carbar 2', which is mounted in the bearings j,

and said bar is provided centrally of its length with a transverse slot similar to the slot k and is adapted to receive a pin 2' carried on a swinging arm, similar to the arm 72, which is provided with a segmental gear i whichis intended to mesh with, and partially rotate the gear 03 The arm it and its counterpart are mounted to swing on a block bearing is secured to oneside of the casing 7), as are also the bearings j. The electromagnets h and k and i and i -are wired in multiple and are controlled respectively by push buttons m and m and n and n mounted in the front wall of the casing g and which operate in connection with normally open terminals 0, 0 0 and 0 In the operation of the device the music is'placed on the frame, as shown in Fig. 1, with the clips 0 and d engaging the upper corners of the sheets f and f at the right,

and when it is desired to turn the music sheet f to the left the push button on is pressed inwardly to close the terminal 0, which establishes a circuit through a conductor p, the electro-magnet h, a main con ductor p and a battery 3 This operation energizes the electro-magnet h, and acts to draw the armature block if to theright which, through the bar If and the pin and slot connection with the arm in, swings said arm to the right and through the instrumentality of the gears h and 0 rotates the shaft 0 to the left, to swing the arm 0", having the music sheet f secured thereto, to the left, as will be readily understood. When it is desired to turn the next music sheet f the push button n is pressed inwardly to close the terminal 0 to establish a circuit through a conductor 9, the electro-magn et z, a conductor 9 the main conductor 2 and the battery y, and this operation energizes the electro-magnet 2', and acts to draw the armature block 2' to the right and through the bar to swing the segmental geari" to the right, which gives the gear (Z a half revolution to the left, and as said gear d is fast with the shaft d and with the arm d it will be seen that the sheet of music will also be carried to the left by the said arm (i as will be readily understood. When it is desired to return the music sheets to the normal position, shown in Fig. l, the push, button-a is pressed inwardly which closes the terminal 0* to establish a circuit through a conductor r, the electro-magnet 71 the main conductor p and the battery y, thus the electromagnet 2' is energized to draw the armature i to the left to reverse the operation, as just described, of the parts 2' 2'", d and d and swing the music sheet f to the right, and inorder to return the music sheet 7 to the right, the push button m is pressed inwardly to close the terminalo and establish a circuit through a conductor 8, the electromagnet b the main conductor p and the battery y, and this operation energizes the electro-magnet 72, to draw the armature block 72; to the left to reverse the operation, as previously described, of the ,parts 72?, 72,

h", 0 c and c and swing the music sheet f,

to the right, as will be readily understood.

Having fully described my invention what I claim as new and desire to secure'by Letters Patent is 1. In a music sheet turner, the combination with a music sheet support of two vertically disposed rock shafts one within the other, gears at the lower end of said shafts, arms pivoted adjacent to said gears and pro vided withsegmental gears engaging said first named gears, reciprocating armature bars which engage said arms and means for reciprocating said bars to rotate said rock shafts in either direction.

2. In a music sheet turner, the combination with a music sheet support of two vertically disposed rock shafts one within the otheiggears at lower end of said shafts, arms pivoted adjacent to said gears and provided with segmental gears engaging said first named gears reciprocating armature bars engaging said arms for reciprocating said bars consisting of oppositely arranged electromagnetic devices In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing witnesses this QQndday of March, 1912.
